SPECIFICATION forming part of Letters Patent No. 773,310, dated October25, 1904.

Application filed February 12, 1903. Serial No. 143,103. (No model.)

To all whmn it may concern.-

Be it known that we, \VILLIAM OUTTERSON lVooD and JOHN HENRY MILLER,subjects of the King of England, residing at South Hetton, in the countyof Durham, England, have invented new and useful Improvements in andConnected with Mining-\Iachines, of which the following is aspecification.

Our invention relates toimprovements in and connected withmining-machines for holing or kirving, whereby such machines are ren-.dered more mobile, more efiicient, and more easily operated.

This invention consists particularly in rendering such a machine moremobile by providing means whereby it may be raised to any desired heightabove the level of the fioor, such means consisting of devicesconstructed on the principle of a screw lifting-jack, provided or notwith wheels or casters. In connection with these raising and loweringdevices a subsidiary frame or support is employed to form an additionalbed-plate of a firm and solid description, such subsidiary frame beingespecially applicable for use when holing in dirt bands in the working.

The invention further relates to means for drilling shot-holes above theplace Where the holing or kirving is being carried out; and it consistsin providing a drill which is revolved by gearing from the engine of themachine, the feed of the drill being according to the forward motion ofthe cutter-chain, the drill being mounted on the sliding frame carryingthe cutter-chain. The bearings in which the drill works may either befixed or they may be mounted in such manner as to be capable ofswiveling and of being fixed at any desired position, so that while thekirving is going on more than one shot-hole may be drilled,whereby asaving of time is effected. Finally, in order that the cuttings anddebris from the under holing or drilling, or both, may be collected andconveyed away from the place where they fall in front of the machine apneumatic conveyer is employed which has a hopper or funnel-shapedcontrivance into which the cuttings fall,whence they are conducted awayby a jet or jets of compressed air through a pipe to the rear of themachine, Where they are collected and carried away.

Figure 1, Sheet 1, of the accompanying drawings represents in sectionalelevationa chain cutter-machine actuated by compressed air and having adrill for drilling shot-holes, part of the conveyer being also shown insection in this figure. Fig. 2 is a plan thereof. Fig. 3 is a sectionupon the line III III, Fig. 1, looking toward the rear of the machine,the subsidiary frame being omitted. Fig. 4 is a section on the line IVIV, Fig. 1, looking toward the rear and with the engine parts omittedfor sake of clearness. Fig. 5 is an end elevation of the machine,showing a section of the cutter-chain upon the line V V, Fig. 1. Fig. 6is an elevation of the machine provided with a modified construction ofdrill for making more than one shot-hole without moving the wholemachine, and Fig. 7 is a front view of the same with some parts of themachine removed to render the drawing more clear. Figs. 8 and 9 aredetail views of the lifting screw-jack, and Fig. 10 is a detailperspective view of the supplementary frames used for raising themachine.

The machine shown in Figs. 1 to 5 is suitably provided with a stationaryprincipal frame or bed (0, consisting of a number of U-shaped supports0, suitablyspaced apart and connected at their lower ends by channel orangle irons d. At their upper ends the members 0 support longitudinalbeams or girders (Z, to which are fixed tooth-racks 7). The beams (Z areformed with longitudinal slots or guideways e for a platform f to slidein. ing frame, and its sides g are formed a sliding fit with the guides(2. At each side of the platform is fixed an engine it, which drivesacrank-shaft 1', supported in bearings in side The platform constitutespart of a slid-' walls or standards/r upon the platform. Upon thecrank-shaft j is fixed a spur-pinion Z and a bevel-pinionm, which gear,respectively, with a spur-pinion a, fixed to a counter-shaft 0, and abevel-pinionp, fixed upon the drillspindle q, which rotates in asleeve-bearing q, the latter being supported in a pedestal 1", fixed tothe sliding platform. A drill s is connected to the spindle r in anyconvenient manner and is steadied in front by a steadying block orbearing 6, supported, by means of a girder t, upon the framing (6. Uponthe counter-shaft is fixed a bevel-pinion a, which gears with abevel-wheel 2:, fixed to a vertical spindle 00, which turns in a bearingformed in a boss in on the platformf. To the lower end of the spindle wis fixed a sprocket-wheel y for driving the cutter-chain A longitudinalmember or plate 1 of the sliding framework is supported at its rear endby the plate f in the following manner: A block 2 is connected with theplate 1 and is provided with a screw-hole. This block is adapted to takeinto a slot or opening 4:111 the plate and a rotatable but non-axiallymovable screw 5, mounted in the plate traversing said opening, passesthrough the screwhole in the block 2. By rotating the screw 5 the block2 is moved toward one end or other of the slot at and effects thecorresponding movement of the plate 1. At its forward end the plate 1 issupported in guides 3, which are fixed to a cross member of thestationary framing a, the edges of the plate 1 being suitably formed toslide in said guides, as shown in Fig. At this end the plate 1 isconnected with a guide or casing 6 for the cutter-chain This easing maybe provided with guide or antifriction pulleys 7 7' for the chain. Sideguides or casings 8 are also provided for the chain, and these aresupported from the plate 1 by transverse braces or arms 9 9. Thus itwill be seen that any relative longitudinal movement of the plate 1 andits parts with the plate f will effect the tightening or slackening ofthe chain The forward support 0 is suitably bowed or bent out at 10,Fig. 5, to permit of the passage of the cutter-chain Side shields 80 arefixed to the stationary framing (a to protect the operators from injuryby the cutter-chain.

The simultaneous feed of the drill and cutter in one direction iseffected by means of a worm 11 on the intermediate shaft 0, with whichworm gears a worm-wheel 12, secured to a shaft 13, adapted to revolve ina sleevebearing 1 1, mounted, by means of a pedestal 15, on the slidingplate f. This shaft 13 has atits other end a worm 16, which gears with aworm-wheel 17, mounted on the shaft 18, revolving in bearings 81 on thesliding plate f and having at each end a pinion 19, which gears with oneof the racks on the principal frame 11.. It is therefore evident thatwhen the engine-shaft 7' revolves and motion is communicated to thecutter-chain motion is also communicated to the drill .s and to thesliding frame. As, however, it is necessary that the sliding frame shallnot only move forward but also backward to withdraw the cuttingchain andthe drill from the hole made in the face of the same, the worm-wheel 17is not keyed to the shaft 18, but may cause the same to revolve with itby means of a clutch 20. If, however, the clutch 20 is released from theworm-wheel 17, it follows that the latter may revolve without impartingmotion to the shaft 18. For imparting motion in the opposite directionto the shaft 18 and at a greater speed than is obtained by the worm 11and worm-wheel 12 the intermediate shaft 0 has secured thereon abevel-wheel 21, which gears with another bevel-wheel, 22, mounted at oneend of a shaft 23, revolving in a sleevebearing 24, supported in theplatef, the shaft 23 having at its other end a worm 25, similar to theworm 16, above described. This worm 25 gears with a worm-wheel 26, andthe latter is loose on the shaft 18, except when it is connected theretoby the clutch. 20. Consequently if the clutch 20 is in gear with theworm-wheel 17 the sliding frame with the engine, the drill, the chaincutter, and the gearing for driving the two lastnamed all move forwardtogether; but if the clutch 20 is in gear with the wormwheel 26 they allmove backward at a greater speed.

In order to raise and lower a machine of the description set forth, weapply two liftingscrews 27, arranged near the middle of the machine orabout at the normal center of gravity of the whole machine. These screwswork in nuts 28, fixed to the principal frame or bed a. The screws arerevolved by alever 29 with a simple box spanner-head. The screw 27 isprovided below with a swiveling fork 30, in which is mounted a caster orwheel 31.

For raising the machine to hole in or kirve dirt bands of varying heightfrom the ground the machine is suitably provided with a number ofunderbases or supplementary frames, of which one is shown. This framemay consist of longitudinal members 32 and crossmembers 32 joined to themembers 32, and may be of wood or iron. The machine is first raised andthen one of the supplementary frames is pushed under the same.

A pneumatic collector and eonveyer of the cuttings and debris is also,preferably, attached to the machine. It consists of a suitable hopper orfunnel 33, into which fall the cuttings or other material, which is thendriven or propolled through a pipe or conduit 84}, by means of aninduced current draft or blast caused by a jet of air, along the conduitinto a suitable receptacle in case of narrow workings and directly intothe goaf or waste in stall work. The said conduit 3% may also suitablybe provided with an arrangement, such as a line spray of water 36, tolay the dust at the point of discharge.

In Fig. 1 the conveyer is shown placed to one side of the maehinein sucha position that the movement of the chain tends to deliver the cuttingsinto the hopper 33. The continuation of the conduit 34: is indicated indotted lines in Fig. 1 for sake of clearness. Instead of arranging theair-jet 35 near to the hopper it might with equal effect be placed nearto thedelivery end of the conduit, as found most plates bolted togetherat a sufficient distance from each other to allow of mounting betweensame the spur-wheels 4:1, 4:2, and L8. Of these the spur-wheel 41 ismounted on the shaft of the bevel-wheel 7), receiving motion by thebevel-wheel m on the engine-shaft. The part 44: of the sliding or cutterframe has circular-shaped slots &5 therein, and the radial arm 40 isclamped at any desired position by means of bolts and nuts a6. Thesteadying-block t is also pivoted as seen in Fig. 6 and is capable ofbeing clamped in position by means of bolts 47 to correspond with theangle of the radial bar 40.
